The temperature in autumn should not be lower than 10℃, otherwise it will be moved indoors, and the temperature in winter will be above 0℃, but not higher than 10℃, otherwise it will lead to insufficient dormancy and affect the next year's flowering.
Kumquat is suitable for growing in fertile and loose acidic soil, and is made of humus soil, sandy soil and cake fertilizer according to the ratio of 4:5: 1. This potted soil is nutritious and well drained.
Extended data:
Fertilization amount is different in different periods. Before the new buds germinate and bloom, dilute sauce residue water should be applied 3-4 times a month and alum fertilizer water should be poured several times. Applying more phosphate fertilizer in summer is helpful to blossom and bear fruit. Stop applying fertilizer at the fruiting stage, and apply liquid fertilizer once a week when the young fruit grows to about 1 cm.
The kumquat should be watered more during the growing period, and the basin soil should always be in a wet state. Water should be sprayed properly in spring and summer, not in flowering period, so as to avoid flowers rotting. Drainage should be done in time in rainy season to avoid root rot.
From flowering stage to young fruit stage, the pot soil should be kept dry and wet, otherwise it is not good for its growth.
